MACHlNE FOR SOLDERING THE ENDS OF TIN CANS.

SPECIFICATION forming part of Letters Patent No. 390,792, dated Qctober 9, 1888.

Application filed June 12, 1888. Serial No. QTQFOD.

To all whom it may concern.-

Be it known that we, SAMUEL W. MCKEN- NEY and FRED. G. KIR'BY, citizens of the United States, and residents of Burlington, in the county of Burlington and State of New Jersey, have invented certain new and useful Improvements in Machines for Soldering the Ends of Tin Cans, of which the following is a specification.

This invention relates to machines for soldering the ends of tin cans, and has for its object the simplification of the machine, enabling soldering-irons and means for conducting molten solder to the can while in the machine to be entirely dispensed with.

Referring to the drawings, wherein our invention is illustrated, Figure l is a front view of the machine. Fig. 2 is a side view, one of the balance-wheels being removed. Fig. 3 is a sectional elevation of the can clamping de-' vices. Fig. 4 is a detail view showing in top view the relation of the can and clampingpressers. Fig. 5 is a sectional plan view of the driving devices for the various vertical shafts.

The operative parts of the machine are mounted in and supported by a frame consisting of the vertical pieces 1, the diagonal crossbraces 2, the top piece, 3, and the longitudinal bars or braces i.

A designates the main drivingshaft of the machine, supported in bearings depending from the bars 4, and receiving its motion from any spitable motor, as through the treadle a and pitman a, connecting the treadle with a cranked portion of the shaft. This shaft is provided at its ends with balance-wheels A and at a suitable point with a sprocket-wheel, A, connected by a chain, A with another sprocket-wheel, B, mounted upon the shaft B parallel to the shaft A, and supported in bearings upon the bars 4.

c is another shaft on the side of the main driving-shaft A, opposite to that on which the shaft B is situated, and supported at one end by one of the bars 4, and near its other in a sleeve, 6, carried by a hanger, 5, depending from the top piece, 3, of theframe. This shaft is driven from the shaft B by a chain, B passing around sprocket-wheels O and B carried by the said shafts respectively. At its inner end the shaft 0 is provided with a bevelwheel, O, meshing with and driving another bevel wheel, 0 carried by a vertical shaft, 0, which (N0 model.)

carries at its upper end one of the bevel-edged pressing or creasing wheels 0 by which the flange of the end of the can is forced against the cylindrical portionthereof.

d is another vertical shaft, also carrying at its upper end a pressing-wheel, D, and driven from the shaft O by the drivechain D, passing around the sprocket-wheels D D, carried, respectively, by the said shafts.

The shaft 0 carries asecond drive-wheel, f, which is connected by the chain E with a wheel, f, upon another vertical shaft, e,which latter shaft in turn becomes a drivingshaft for a fourth vertical shaft, 6, such shafts being provided, respectively, with pulleys E E, connected by a driving-belt, E while the shaft e is provided at its upper end with a plate or disk, G, upon which the can is supported during the operation of soldering the ends thereof.

The relations of the gearing and shafts thus far described, as to speeds, &c., may be varied as circumstances may require; but we prefer to have the shaft carrying the can turn three times to each revolution of the shaft B, which latter shaft operates the devices for releasing the can to permit its removal, as will be presently described.

Supported above the top piece of the frame are two uprights, 11 and 12, connected at their upper ends by a cross-piece, 10, and supporting abracket, 13, in which is mounted a vertically-arranged springactuated rod, F carrying at its lower end a plate or disk, F, adapted to bear upon the head of the can and hold it firmly upon the plate G.

G is a horizontally-arranged sliding rod mounted in bearingsg at the front end of the top piece, 3, of the frame, and carrying at its front end a beveled bearing or pressing wheel, G, adapted to engage with the can and, in conjunction with the wheels (1 and D to press the flange of the top or cap piece of the can against the cylindrical body portion thereof, the horizontal relation of these three presserwheels to each and to the can being shown in Fig. 4.

G is a spring mounted upon the rod Gfibetween one of the bearings 9 thereof and an adjustable stop, 9, carried by the rod and tending to force the rod and with it the wheel G toward the plate G.

It will be seen that upon elevating the rod F and the plate which it carries, and upon ICC withdrawing or forcing backward the rod G and its bearing-wheel, a can may be placed upon the plate G,between the stationary wheels or rollers G and D against which it will be forced and held by the spring-actuated presser wheel or roller G when released, while the plate F", bearing upon the top of the can, under the pressure of the spring F will hold it in place upon the plate G. In order that these can-holding devices may be worked automatically to clamp and to release the can to be operated upon, we make use of the devices which will now be described.

F is a lever pivoted at :13 in a bracket sup ported on the lower face of the top piece of the frame and engaging at its upper end with the rod Gfiwhich is slot-ted to receive it, while its lower end extends downward past the shaft B,and is acted upon by a cam or arm, F. carricd by the shaft, so that the lever and its connections are actuated at each revolution thereof.

, F is a link connecting the lower arm of the lever F with a bell'erank lever, F, which in turn is connected by a link, F, with a lever, F fulcrumed in a standard, F carried by thecrosspiece 10 of the standards 11 and 12, which latter lever is connected with the sliding rod Fto reciprocate it as it is moved. It will be seen that as the lever F is moved in the direction of the arrow, Fig. 3, at each revolution of the shaft B, the rod G and wheel G, and the rod F and plate F are simultaneously moved away from the can resting upon the plate G, to be again forced into coir tact therewith by their respective springs as soon as the cam or arm F passes out of engagement with the lever F.

()n the rear portion of the top piece, 10, of the frame, opposite the rod G- is arranged the burner II, by which the solder which has been previously applied to the can, preferably by the apparatus described in our application filed June 12, 1888, Serial No.27li, 808,is melted. The flame from this burner is directed to contact with the can at the proper point by the deliecting-plates II and HP, the lower one,H, of which is preferably mounted stationarily between the uprights 11 and 12, while the upper one is made adjustable vertically, being operated by means of the rod H" and, adj usting-nut H.

The operation ofthe machine will now be described. The can, the edges of the cylindrical body portion of which have been coated with solder, preferably both inside and outside, by the abovereferred-to apparatus, and the end piece which is to be soldered thereto having been fitted to its place, is placed upon the plate G, upon which it is held by the plate F", and clamped by the pressers O, D, and G.

The shaft A being driven, the can is given a rotary motion on its vertical axis, the relative speeds of the various parts being such, as hereinbefore stated, that the can is rotated three times to each reciprocation of the rods G and F. The flame from the burner directed by the deflectors plays upon the can near the lower edge during its revolutions and melts the solder, which runs down between the flange of the end piece and the outside of the cylindrical body portion, and also down upon the inside of the body portion of the can, while the flange is being pressed against the side of the cylindrical end of the can by the bevel-edged pressing-wheels. At each reciprocation of the rods F and G the can, the end of which has been completely soldered on, is released and may be removed and replaced by another, when the same operation will be repeated.

1. The combination of the can-support, the presser wheels or rollers 0' and D", mounted by the side of the cansupport, the driving mechanism for rotating all of the said parts, a mova ble clamping-plate mounted opposite the can support, the movable presser mounted upon a sliding support arranged adjacent to the cansupport, and a lever for reciprocating the support for the movable presser automatically, substantially as described.

2. The combination of a can-support, rotary pressers, the movable clamping plate, the movable presser, a driven shaft, 0, connected to rotate the can-support and the rotary pressers, and a driven shaft, B, connected to reciprocate si m ultancously the movable p resser and clampingplate, substantially as set forth.

3. The combination of the rotatingcan-support, the rotating pressing wheels or rollers, a shaft from which the said rotating parts are driven, a presser, G, carried by a sliding rod, a lever connected to move the rod, and an arm on the driving-shaft which rocks the lever, substantially as described.

4;. The combination of the rotating can-support, the can-clamping pressers, one of which is supported by a reciprocating rod, G, the plate F, carried by a reciprocating rod, linkandlever connections between the said reciprocating rods, and an intermittcntlyacting arm carried by the driving devices acting upon the said connections to impart simultaneously reciproeations to the said rods, substantially as described.

5. The combination of a can'support, the can-clamping pressers, a burner, and an adj ustable deflector for the flame of the burner, substantially as described.

6. The combination of the eansupport, the clamping-plate mounted opposite thereto, the presscrs adj aeent to the can-support,the burner also adjacent to the can'support, and the deflectors which direct the flame from the burner upon the can adjacent to the pressers, substantially as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
